Just ask a question, like, 'How many cowboys does it take to operate an airliner' or 'How many vegetarians does it take to eat a meat pizza'. Something like that. The next person will answer the question.
Here's an example, one that I made off of Seven of Nine's question in the Ten Forward Lounge.
How many programmers does it take to buy ice cream?
It takes 9 programmers to buy ice cream:
1 to calculate the amount of ice cream required.
1 to program a shopping cart the right size for the carton.
1 to program a script to open and close the freezer door.
1 to program a MOD for different Ice Cream flavours.
1 to program a script to easily select and grab Ice Cream cartons.
1 to calculate a path through the store for the shopping cart.
1 to program a MOD for self-checkout, including bar code scanning and credit card slider.
1 to program a bag the right size for the carton.
1 to program an extension to the car so that all of them, including the Ice Cream carton, will fit.
And now, for the first question!
How many midgets does it take to dunk a basketball on an 8-foot hoop?
